Channel Expansion Function
(See section 10.6 for the procedure)
Allows the master unit to handle up to 10 channels. A program file in which the channel
expansion is defined is loaded into the master unit and distributed to the slave units
via the Ethernet network. After a measurement is completed, the stored results can be
consolidated into a single file (Result.csv). This function can be used when sourcing
voltage or current and making measurements in an application that requires three or
more channels to be operated in sync. For example, it can be used in the electrical
characteristic measurements and GO/NO-GO tests of multiple-pin electronic devices,
multi functional semiconductor ICs, electronic circuits, board assemblies, and the like.
Channel expansion is not possible when there is a mixture of 18 V models and 50 V
models.
